As far as I am aware the a/c reported a rough running engine, which soon became a double engine failure. The pilot apparently got one of the engines started again and was heading towards the cherbourg coast when it failed a 2nd time. The a/c did have a liferaft which the survivor was found in, the other 2 were found face down in water. The a/c was originally routing cvt-gci, my sincere condolences go to all the families and praise to those involved in the rescue.
